Oof that's old.
The original bug might have been at least partially closed, I now don't
see this as much as I used to in code buffers (but it might equally have
been a change in my config). However I do see this *a lot* in tex files,
reproductibly, and it's still very annoying. I'd love it if this was
fixed!
Here's a reproducer from emacs -Q (just reproduced on 27.1):
Set
(setq scroll-conservatively 100000000)
(setq scroll-preserve-screen-position 'stay)
Open a latex file of some complexity (with sections and math, for
instance https://arxiv.org/e-print/2003.00726, but it works on any tex
file), and make sure it's in latex-mode. Go somewhere in the middle of
the file, center point (C-l), then scroll up then down (C-v and M-v).
I traced it down to
lines of varying heights: it disappears if I set
(setq font-latex-fontify-script nil)
(setq font-latex-fontify-sectioning 'color)
Best,
Antoine
